IPA: /ˈæftərɡloʊ/
KK: /ˈæftərˌɡloʊ/
A soft light or pleasant feeling that remains after something has ended, like the light in the sky after the sun has set or the good feelings after a happy event.
The afterglow of the sunset painted the sky in beautiful hues of orange and pink.
Afterglow is formed from "after" (from Old English "æfter", meaning following in time or place) and "glow" (from Old English "glōwan", meaning to shine or emit light). The word describes the light or radiance that remains after the sun has set or after a significant event has occurred.
Imagine the light that remains 'after' the sun has set, which helps you remember that 'afterglow' refers to the lingering light or warmth following an event.
